I copied entrust Zizaco\Entrust\src\config\config.phpto my proyect\app\config\entrust.phpand I modified the file test\vendor\zizaco\entrust\src\Entrust\EntrustServiceProvider.phpin this method:

我将委托复制Zizaco\Entrust\src\config\config.php到我的proyect\app\config\entrust.php并test\vendor\zizaco\entrust\src\Entrust\EntrustServiceProvider.php在此方法中修改了文件：

  private function registerCommands()
    {
        /*
        $this->app->bindShared('command.entrust.migration', function ($app) {
            return new MigrationCommand();
        });
        $this->app->bindShared('command.entrust.classes', function ($app) {
            return new ClassCreatorCommand();
        });*/

        $this->app->singleton('command.entrust.migration', function ($app) {
            return new MigrationCommand();
        });
        $this->app->singleton('command.entrust.classes', function ($app) {
            return new ClassCreatorCommand();
        });
    }

This resolved the issue for me.

这为我解决了这个问题。

vendor/zizaco/entrust/src/Entrust/Traits/EntrustRoleTrait.phpat line 51 makes the call Config::get('auth.model')as the first parameter to the $this->belongsToMany(method call.

vendor/zizaco/entrust/src/Entrust/Traits/EntrustRoleTrait.php在第 51 行，将调用 Config::get('auth.model')作为$this->belongsToMany(方法调用的第一个参数。

public function users()
{
    return $this->belongsToMany(Config::get('auth.model'), ...
    // return $this->belongsToMany(Config::get('auth.model'), ...
}

You can either change this to Config::get('auth.providers.users.model')or update your config/auth.phpfile to include an entry model => App\Users::class

您可以将其更改为Config::get('auth.providers.users.model')或更新您的config/auth.php文件以包含一个条目model => App\Users::class

'model' => App\Users::class,  

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\Users::class,
    ],
],

My preference is to update the config/auth.phpfile since any changes to the vendor folder will not be available to others on your team, or when you move to production.

我的偏好是更新config/auth.php文件，因为对供应商文件夹的任何更改都不会对团队中的其他人可用，或者当您转移到生产时。

Of course if you are using a different Model for your Users you would supply that instead.

当然，如果你为你的用户使用不同的模型，你会提供它。

Entrust hasn't been upgraded for 5.2 yet so you need to fiddle around with it a little.

Entrust 尚未针对 5.2 进行升级，因此您需要稍微处理一下。

As tapos gosh has said beforeyou need to go in to vendor/zizaco/entrust/src/commands/MigrationCommand.phpand on line 86:

正如tapos gosh在您需要进入vendor/zizaco/entrust/src/commands/MigrationCommand.php第86行之前所说的那样：

Remove

消除

$usersTable  = Config::get('auth.table');
$userModel   = Config::get('auth.model');

And replace it with

并将其替换为

$usersTable  = Config::get('auth.providers.users.table');
$userModel   = Config::get('auth.providers.users.model');

And then in config/auth.phpfile write the provider line like so:

然后在config/auth.php文件中写入 provider 行，如下所示：

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\User::class,
        'table' => 'users',
    ],

    // 'users' => [
    //     'driver' => 'database',
    //     'table' => 'users',
    // ],
],
